/* glyph :: A handle to a target slot object where the glyph */

/* must be scaled/loaded. */

/* glyph loading process (e.g., whether the outline */
/* should be scaled, whether to load bitmaps or not, */
/* whether to hint the outline, etc). */

/* result :: A set of bit flags indicating the type of data that */
/* was loaded in the glyph slot (outline or bitmap, */
/* etc). */
/* */
/* You can set this field to 0 if you don't want this */
/* information. */
